limiting movementof the roof sheets trans-Y versely of the car. i

Other objects and advantages of the invention together with the numerous novel details of construction will become more apparent as the following description proceeds, particularly when reference is had to the accompanying drawing wherein,

Figure l is a fragmentary plan viewA of a same;

Figure 2 is a transverse sectional Vview through a portion of the carroof shown in Figure l;

Figure 3 is a fragmentary sectional viewV taken substantially on the line 3 8 of Figure l Fighre 4 is a fragmentary sectional view taken substantially on the line 4-4 of Figure l' Y Figure 5 is a fragmentary sectional view showing the connection of the roof sheets at i the eaves of the roof, and

Figure 6 is a fragmentary sectional view taken substantially on the line 6--6 of Figure 1.

ln the drawing there is disclosed a car roof, the supporting frame of which includes a ridge pole A, side plates B and a number of purlines C arranged between the ridge pole and side plates. In the type of roof disclosed, wooden sheathingD is shown as being supported on the ridge pole, purlines and side plates, this sheathing forming a wooden roof for the car. It is to be understood, however, that the invent-ion is not limited t0 this particular type of roof since the inventive principles. involved will find equal utility in a car roof in which the metallic roofing sheets are self-supporting and are mounted directly on the roof frame.

In the construction disclosed roof sheets E are arranged on opposite sides of the'ridgel pole, each sheet extending from the ridge of Y the car to one of the eaves thereof. These roof sheets are supported for movement relative to eachother to compensate for weaving of Ithe car roof during movement of the car.4

and accordingly each roof sheet is provided at its outer edge adjacent the eave of the car with a return bent flange'F adapted to fit in a pocketformed by the reversely bent portion G of a flashing strip H which is secured in any-desired manner to the fascia I which in turn is secured with the yside sheathing J to the side plate B. Thus each roofing sheet is loosely held down at the eave of the car while provision is made for movement of the. roofing sheet transversely of the car. car roof showing the invention applied to the The roofing sheets are positionedbetween mulhons K arranged in spaced relation Aupon the roofing boards D and secured thereto.

At their opposite sides the rooiing sheets arevr provided with Vflanges L terminating in inwardly and downwardly extending portions VM, these portions being spaced from the sides of the mullion strips as illustrated in Figure 3. Forming the joint between the side-s of the reversely bent portion of the flashing strip Vl-ll as clearly illustrated in Figure 2 of the drawing. j

Adjacent the ridge pole each roofing sheet is provided with a marginal portion bent to form an inverted channel. Thus as clearly illustrated in Figure 4 of the drawing, each Vroof sheet adjacent the ridge pole is bent upwardly as at O and then forwardly and downwardly to provide an inverted channel shaped marginal portion which may be engaged with the channel shaped marginal portion of the corresponding sheet on the opposite side of theridgepole in the manner illustrated. Thus Vcorresponding sheets on opposite sides of the ridge pole are detachably connected to each other at the ridge pole, the marginal channel shaped portion of one roof At the juncture of every four roof sheetsl at the ridge of the car, center caps Q are provided, these center caps embracing adjacent ridge caps and adjacent transverse'caps in the manner clearly illustrated in Figures l and 2 of the drawing and these caps form supports for a runiiiiig-board saddleR which in turn supports the usual running-board S.

Bolts T extend through the running-board? saddle and the center caps andf'are anchored wridgehpole, and means fixed to said iidgepole vin the ridge pole orholding the center `caps and runniiig-board saddle inposition.

5F or supporting themarginal porti'onsofl the root sheets adjacent the ridge pole and for limiting transverse movement oiitheroof sheets, members U are provided, each mem-4 ber U comprising a short section of an inverted channel bar which isy anchored to the ridge pole by the bolt T. i Each-member U extends between the aceiit ends of aligned inullions 'and projects into the channel formed by the 'inverted channel portions of adjacent roof sheets. Thus as clearlyeillustrated in Figure 1 of thedrawing, opposite ends of the member U extend into the chan nels formed by the marginal portions ofthe is of slightly less cross section than the channel portions of the roof sheets to permit a slight movement of the roof sheets' transversely of the car roof but being tixedrto the ridge pole limits movement of the roof sheets `transversely of the car roof.

From the above it is believed that theinvention will `be clearly apparent. The' roof sheets are looselyv supported whereby lthey -may yield to compensate for the weavingof the car roof. At the juncture ofA :tour adjacent root sheets at the ridge 1 of the cai', the l `members U are vprovided 'and these members l by engaging the under sides of the marginal channel shaped portions otthe adjacent roof sheets, support these portions ofthe roof sheets at the ridgeoiC the car and also vby engaging the sides of the channel shaped 'portions of the roof sheets, liniittransverse movement of the roof sheets. Byl arrangeing the member U in the manner disclosed, one member U will support four'roof sheets and will limit transverse movement of'fall four of vthese roof sheets, thus ieducingtoa minimum the cost and labor incident to' the I b'er xed Ato said ridge pole and engaging the" inter-'engaged marginal portions of said roof l-understood that the descriptionis' for' the j j purposes of illustration only-and"-i's1not"de-` `liiiitive of ythe limits of the inventive idea.

The memberi U tending from the ridge of the car to one of the eaves thereof, and member iixedly mounted at the ridge of the car for supporting the 'root sheet, while providing for a limited movement ot the roof sheet transversely of ythe car at the ridge thereof.

2. In a flexible car roof, a ridge pole, a roof sheet extending Vfrom the said ridge pole to one of the eaves ot the ca r, said roo'l sheet being. provided with -an inverted channel shaped: marginal portion adjacentI the said and extending into the channel portion of Asaid'roof sheetiin 'engagement with the base -vsheets arranged on opposite sides 'of' said ridge pole, and a member fixed tosaid ridge pole and engaging the marginal portions of adjacent roof sheets for supporting `said roof sheetsadjacent said ridge pole, saidvmeinber having portions normally spaced from 'portions of said roof sheets adapted to limit Vtransverse movement of said roof sheets.

4ta-In av iexible car roof, a ridge pole, roof sheets arranged on opopsite sides of said 1 ridge pole, each of said roof sheets being pro vided withI an inverted channel shaped inarginal portion adjacent said ridge pole, the

channel shaped marginal portions of the roof yportions of the corresponding roof sheets on `the opposite side of lsaid ridge pole, anda member fixed to said ridge pole at the juncture of four of said root sheets and engaging 'the bases of the channel shaped portions of said roof sheets for supporting said roof -sheets,- said'fmember having side: `portions spaced trom the sides ot' the channel shaped? vmarginal portions of the roof sheets adapted l to limit movement of the roof sheets transversely of the car. v
